Study Notes
Anatomy vs. Physiology
- Anatomy studies the body's structures and their interrelationships.
- Physiology focuses on the chemical and physical processes that enable body functions.
Levels of Organization
- Six levels of biological organization:
- Chemical: Subatomic particles, atoms (e.g., hydrogen, lithium).
- Cellular: Basic unit of life (e.g., muscle cells, nerve cells).
- Tissue: Groups of similar cells (e.g., epithelial, connective, muscle, nerve).
- Organ: Structures composed of tissues (e.g., skin, heart, kidneys).
- Organ System: Groups of organs working together (e.g., skeletal system, digestive system).
- Organism: The complete living entity (e.g., a human).
Characteristics of Human Life
- Metabolism: The sum of all chemical reactions in the body.
- Growth and Development: Increase in size and changes over time.
- Adaptation: Ability to adjust to environmental changes.
- Reproduction: The process of producing offspring.
- Response to Stimuli: Reacting to internal and external changes.
- Homeostasis: The maintenance of a stable internal environment crucial for normal functioning.
Homeostasis
- Defined as maintaining stable conditions despite changes in the external environment.
- Involves three components:
- Receptors: Detect changes in the environment.
- Control Center: Compares changes to a set point and processes information.
- Effectors: Muscles or glands that execute response adjustments to restore balance.
Anatomical Position and Terminology
- Standard anatomical position:
- Body standing upright, feet shoulder-width apart, palms and toes facing forward.
- Directional terms used in anatomy:
- Sagittal (median): Divides the body into left and right portions.
- Mid-sagittal: Divides the body into equal left and right halves.
